Undulator Assembly Procedure LCLS Review 11/15/04 Mark Erdmann
Mark Erdmann / LCLS Review Assembly Plan LCLS will provide strongbacks, poles, and sorted magnets to assembly vendor Assembly vendor will fabricate remaining parts Assembly will be according to LCLS procedure 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Assembly Procedure Closely follows experience of prototype assembly Improved and simplified by value added engineering changes Poles with a more basic design but tighter tolerances Pole sorting not required One piece base plate versus 3 pieces Assembly can easily be performed by mechanical shop without previous undulator or permanent magnet experience 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 1: Check 10% of incoming poles to verify they meet the height specification. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 2: Attach 1st pole assembly fixture to the magnet / pole base plate. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 3: Install poles onto the base plate, starting on the upstream side. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 4: Attach 2nd pole assembly fixture and continue installing poles until entire magnetic structure is full. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 5: Obtain magnetic field data from manufacturer and sort magnets. Manually install magnets and clamps. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Step 6: Assemble the top and bottom magnetic structures using the assembly fixture. 12/2/2018 Mark Erdmann / LCLS Review
Mark Erdmann / LCLS Review Conclusions This assembly procedure has been proven to work on the prototype LCLS undulator. Manual insertion of permanent magnets is a safe and reliable method of assembly. Method can easily be transferred to industry for large quantity assemblies. 12/2/2018 Mark Erdmann / LCLS Review
